Dazai and Atsushi became illegal.

 

They were both alphas.

 

OR: Dazai bitches Atsushi. Lots of worldbuilding and swearing. Smut everywhere I could insert it.

Chapter 1: The Hierarchy Protection Regulation

Chapter Text

The laws didn’t allow alpha-alpha or omega-omega relationships. Alphas and omegas were forced to breed with each other. Any relationship considered a risk to their survival was judged as a crime.

The Hierarchy Protection Regulation was approved by absolute majority in the government; supported by alpha, beta and omega politicians.

 

Alphas were born to rule the world. They were merciless, intimidating, dominant. His pheromones could make an omega submit without saying a single command.

Their anatomy developed to put in place whoever they wanted. Through the most primal procedure: sex. Strong bodies, inhuman stamina, little fangs to bite.

Their cocks were larger and wider than any other human beings. The base had a knot, a bulge that inflated bigger than a fist size when they reached orgasms. It made it impossible to take the cock out of the hole without tearing it.

It was a breeding evolution, to assure the seed would take. And another form of domination. Having someone knotted at their mercy for half an hour, and marking them from the inside. Alphas produced huge amounts of semen.

 

Omegas were born to be the exact opposite. To be used, to be bred, to carry the legacy. Their personality was quiet, obedient, submissive. They craved the feeling of pleasing an alpha, especially during sex.

So, their bodies accommodated that purpose. Needy, easy to handle, lack of gag reflex. When they wanted to be fucked, they would naturally present, spread their legs and arch his back, a position that displayed the best they had to offer: a hole.

Their cocks were mere decoration, smaller than average and with tiny balls that barely produced cum. Instead, the inside of their ass was full of special glands that discharged slick as a natural lubricant, along with a dilation and inflammation of the hole.

This submission wasn’t degrading, though. Omegas got hard by the sole thought of worshipping their alpha, and the anal stimulation was the only way for them to orgasm. Being knotted or marked made them proud to be owned.

 

Alphas and omegas needed each other. Once a month, they lost control of their instincts and enter a rut or heat. Alphas needed to knot an omega, omegas needed alpha’s cum. If the intercourse didn’t happen, their health would deteriorate to the point of eventual death.

In the past, the alpha-omega relationship was driven by those pure instincts. Omegas weren’t treated as humans, but sex-slaves that were abused and punished to fulfil the alpha superiority complex.

The situation changed over time. Alphas and omegas rioted together to achieve equal rights. Society no longer cared about omegas studying and working, nor who fucked who, as along as boundaries and desires were respected.

 

And that became a problem.

 

Nowadays, most of the population were betas. Just basic people, that hadn’t developed a secondary gender. They could give birth to alphas and omegas, but the genetics weakened every time, so their mixed children were considered defective.

It wasn’t really an issue, if not for the ruts and heats. The alphas and omegas weren’t able to satisfy their needs. They were getting sick. They were dying. They were getting extinct.

The result was the Hierarchy Protection Regulation, designed to strengthen the original genetics. It encouraged the alpha and omega former social roles, as well as alpha-omega natural breeding.

 

So.

Dazai and Atsushi became illegal.

They were both alphas.

 

Dazai came from a traditional family. A long genetic heredity of purebreds. He was the perfect alpha. Born to be worshipped. His powerful scent could frighten even betas.

His cock was the usual length for an alpha, although its width was insane, and his cum accumulation was almost painful. Atsushi needed lots of prep to take him, and Dazai refused to knot him, although his partner wanted to try some times.

Atsushi, however, was a mixed alpha. Born to be useless. Despite knowing nothing about his family, he had a knot and ruts. He had quite the temper and he was possessive as fuck. Yet he liked to submit willingly to Dazai.

His body leaned on his beta side. His cock was barely in the alpha spectrum, and his knot was small and didn’t last long. It was an advantage when he fucked Dazai, although most of the times he’d rather be fucked.

 

Atsushi and Dazai had a healthy, modern, respectful relationship. Dazai rejected his conservative family behaviour and Atsushi was an independent and proud defective alpha.

Every month, they used a brothel to knot some omega nobody. They fucked the same one, and they got rid of the smell marking each other after it.

At home, they were free to explore their sexuality as they wanted. They were into some role play, and the dominance or submission was always consensual.

 

Dazai used to be a lonely alpha that didn’t do relationships, taking pleasure in making an omega submit from time to time. Until he met Atsushi. The wittiness yet soft personality of the other alpha got him obsessed.

Atsushi fell in love with Dazai at first sight. He wanted a loyal partner, his abandonment issues made him jealous and caused trouble in past relationships. Dazai’s overprotection was exactly what he wanted.

They’d been together for one year. They began dating some months after Atsushi was hired in Dazai’s cyber investigation business.

No one knew. A boss fucking his subordinate was more frowned upon, than an alpha fucking another alpha.

 

Until now.

 

They were shocked when the Regulation was approved, and alpha-alpha relationships were forbidden.

They understood the reasons. Atsushi could easily spend a few ruts without knotting. Dazai was the one at risk of getting sick.

They were lucky Dazai was a successful businessman and he had access to some last-minute whores. Even so, many times they had to fuck women, because they were much more available omegas.

 

Because the thing was… they were gay.

They couldn’t breed even if they were alpha and omega.

Alpha females and omega males were infertile.

 

The new laws didn’t take that situation into account. It assumed pure alphas and omegas would ditch their current partners, and become straight for the sake of humankind, or something.

“FOR FUCK’S SAKE!” Dazai’s phone flew through their bedroom and crashed against the wall.

It was early morning. They were still in bed, reading the latest news. The Regulation came into effect that night.

 

The first couple was arrested. A famous influencer and her girlfriend. Both omegas. They’d be forced to break up and find alphas to mate.

 

“Get out of bed and check if your phone is still alive. I can’t buy you a new one every month” was Atsushi’s lazy answer to his partner’s tantrum.

Enraged, Dazai jumped out of bed, and began pacing around the room, not caring about the device at all. He looked like a demon, with his messy black hair and his baggy black pijamas.

“So we’re criminals now, huh? Well, then I’ll become one-”

“Osamu.”

“I’m going to fucking kill everyo-”

“Osamu!”

The man stopped, as in sudden realization. He looked at Atsushi for a minute straight, clenching and unclenching his fists.

The other alpha was still staring at his phone. His white bangs fell like a curtain over it, so focused he was on reading. The sunlight made his naked skin shine like an angel.

The room smelled softly of his delicious roasted green tea scent.

Dazai’s fists trembled.

“Why are you so relaxed? Are you leaving me?” he whispered.

“What? No!” Atsushi looked back at Dazai. “Stop that. You’re suffocating me”

Dazai’s scent had changed from his usual smoke, to gasoline, to burnt paper.

Calm, angry, anxious.

“I’m thinking about that option the doctors suggested for people like us”. Atsushi said, then shut Dazai up by lifting a finger when he tried to retort. “I know you’ve read it too. And I know you won’t agree. I… I wouldn’t mind trying.”

“No.”

“We need to do something. You’re a big one in the market. They'll force you away from me, and whore you out to some perfect pure omega, to breed your perfect pure fucking children”

Atsushi’s green tea started to smell like dry leaves. The idea of someone else touching his partner without consent was infuriating.

Dazai noticed the change. Gathering all the patience he had left, he let Atsushi continue.

“The procedures are reversible. If the law gets revoked, and we’re not satisfied with the results, I’ll go back to who I am now”

“No.”

“Please. Love. Listen. I mean it. We role-play about this all the time. You’d love to have an omeg-”

“I love you!”

Dazai snapped. He jumped back to the bed. He pinned Atsushi down with his body and grabbed him by the jaw.

His eyes were black. His fangs were out. He lowered his voice until it was almost a threat.

“I won’t allow you to mutilate your body to protect me.”

Atsushi couldn’t move. The gasoline set the leaves on fire. His heterochromatic eyes stared into the void, like flames shining in the dark. He couldn’t breathe.

He gasped for air.

Dazai’s eyes widened.

The powerful alpha retreated to the end of the bed. He covered his face with his hands, and breathed in and out to calm himself.

Atsushi laid still until Dazai’s effect wore off. He hesitated a moment before crawling slowly through the mattress.

Dazai muttered:

“I’m sorry, love. I’m distressed”

“I know”

Atsushi took Dazai’s hands, removed them from his face, and squeezed them.

 

Then he slapped Dazai.

 

“First of all, you allow me nothing. I’ll do whatever I want. I belong to me, above belonging to you”

Atsushi caressed Dazai’s face where it was turning red. His partner hated pain.

“Being an omega is not a mutilation. Drop that classist alpha bullshit you grew up with”

Dazai frowned. The mention to his family hurt him more than the slap.

“And. Of course I’ll protect you. I’ll protect us. My body is yours as much as your body is mine”

Atsushi kissed Dazai’s cheek.

“I’m sorry, too. I love you, too”

Both of them regretted their behaviour immediately. That was the problem of being two alphas, their nature clashed sometimes.

“I need a cigarette”

“I need breakfast”

 

Citizens complained about the Regulation since the moment it was proposed. The government ignored the lawyers and anthropologists reports. Going back to the old hierarchy was the only solution.

So the scientists researched how to make things legal for same-gender couples. Two ancient practices, banned a long time ago, were accepted as an option. A 2-week period was given to alphas and omegas to choose if they wanted to take them.

Studding, turning an omega into an alpha; bitching, turning an alpha into an omega.

Studding was easier. A surgery existed. Anal glands removal, knot transplant, hormonal boost. The body would adapt and become the one of an alpha by itself.

Bitching, though. The only way to achieve it was a humiliating and extremely painful natural process.

The stronger alpha had to force their partner to submit by knotting. Alphas weren’t made to endure it. Even another alpha cock was painful to take. It was possible thanks to lubrication, stretching and patience.

Dazai and Atsushi were quite the sadist and masochist type, so sex was not an issue. But fucking forcefully would be agonizing with Dazai’s endowment. And knotting, near impossible.

 

“There’s rumours in the office, you know?” Atsushi yawned, now dressed with a crappy tshirt too big for his small frame, as he squeezed some oranges.

“I’m the boss. No one tells me the office gossip” Dazai pouted, waiting for the coffee to finish brewing.

Although Dazai’s flat was big, like everything concerning him, the kitchen was the exception. The two men bumped into each other sometimes trying to work in it.

At least it was open-plan, so they fitted a table in front of the aisle, between the kitchen and the modern living room.

“People notice you don’t treat me as badly as the other employees.” Atsushi continued. “Don’t look at me like that. It's not my fault you’re an asshole of a boss. Anyway, we can’t hide forever. Someone will snitch on us.”

Atsushi wondered if he should keep talking.

“Also, people talk about you. It’s weird that a pure alpha like you still don’t own an omega”

Dazai tensed. Atsushi cursed to himself. He walked to Dazai and rubbed his back.

“They don’t understand, love”

“Why you?” Dazai said abruptly. “Why not me?”

Atsushi’s hand froze. Unbelieving.

“Do you really think you can be bitched by me?

Dazai shrugged his shoulders. Atsushi let out a soft laugh. He cornered Dazai against the fridge and ran his fingers through Dazai’s neck.

“You’re afraid of being an alpha. Because you think you’ll lose me. It won’t happen again”

“Don’t mention him. Even if you’re right”

His words were gentle. Atsushi kissed Dazai softly. A silent apology.

What an absurd thing to feel. Being jealous of someone dead.

 

They sat at the table knowing that more feelings would be hurt. The conversation was unavoidable.

“I’m afraid of you being an omega, too,” Dazai stated. “I like when we role-play, and yes, of course I fantasize about owning you, I can't help it. I’m concerned because it’d be real

Atsushi took a sip of the orange juice and kept the glass in his hands, holding it firmly.

“Sometimes…” he started. “Sometimes I wish I were an omega. I know you can’t fully understand it, and that’s ok. But I really meant it when I said I wouldn’t mind.”

Dazai's face showed a bit of shame when he asked:

“What if that desire is just a side effect of my pheromones?”

“No. For sure. I thought about it before dating you. I don’t like being half an alpha. I feel like I’m nothing. I want to be something”

Atsushi was staring at the orange juice. Dazai put his hands over Atsushi’s and placed the glass on the table. He spoke with conviction.

“That’s what you were told when you were a child. That fucking orphanage made you believe you’re nothing. You don’t need to be an alpha or an omega to be worth loving. I love you as you are”

Atsushi raised his head and intertwined his fingers with Dazai’s.

“I’m proud of who I am, now, thanks to you. I don’t want to lose this. Becoming an omega would be just fulfilling an old wish. Nothing else. It doesn’t bother me”

Dazai leaned closer to Atsushi until their foreheads almost touched.

“Look me in the eyes. Tell me you’re not doing this for me”

“I’m not doing this for you,” Atsushi repeated.

Dazai fixed his dark eyes in Atsushi’s rainbow ones. He stared without blinking, searching for something he didn’t find.

Then he sat straight again and began eating.

“I could dump you,” Dazai joked.

Atsushi grabbed a knife and pointed it to Dazai.

“I could kill you”

They both burst into laughter. The atmosphere was still tense, but their love was unbreakable.

“I have a fear,” Atsushi admitted. “About personality changes. I don’t want to become one of those brainless desperate omegas we fuck on ruts”

Dazai dropped the clutery.

“That’s the heat. You won’t be like that the rest of the time. You’ll keep your independence, love. And I’ll take care of you in your heats. Do you trust me?”

“I trust you”

“You shouldn't,” Dazai said.

“What?”

“I’m a fucking sadist, Atsushi. I enjoy it. I’d have you impaled on my cock 24/7. I’d slap you until you cry because I love your wrecked face. I’d make you beg for the privilege of me spitting on you. I’d…”

“Stop. You’ll make me hard” Atsushi interrupted.

“What?”

“I’m a fucking masochist, Osamu. I enjoy it.” Atsushi mimicked Dazai.

They laughed again. Actually, their trust was unbreakable too.

“Now…” Atsushi checked that the breakfast was finished. The dishes will have to wait. “Get up. This is my last chance to fuck you”

“Wait. I didn’t take a shower yet”

“The fuck I care!”

 

Well, Dazai cared. So they ended up in the bathroom. A long room with a huge shower taking up the space of a whole wall.

Dazai pushed Atsushi against the sink and nipped at his lips. The kisses were rough and demanding. They tasted the breakfast in each other's mouth as their breathing became faster.

Dazai lifted Atsushi’s tshirt and ran his hands through the alpha’s small body, which he could trace from memory. He stopped at the nipples and pinched one of them. Atsushi hissed.

Dazai picked up Atsushi by the ass and sat him on the countertop. Atsushi took advantage of the moment to get rid of the tshirt, while Dazai yanked the underwear and tossed it on the floor.

The stone was cold under Atsushi’s cheeks. A contrast with his cock, that was palpitating with need.

Dazai grabbed the tip and brushed its underside with his thumb, spreading the precum. It wasn’t enough to slide his hand, so he crouched in front of the sink and took Atsushi’s warm in his mouth.

A streak of pleasure sent shivers down Atsushi’s spine. He threw his head back and moaned. Then he held Dazai by the hair, not encouraging him, but pushing him away.

“The… ah… the shower!”

Dazai let go of Atsushi’s cock, and looked at him grinning. He ran his tongue along one of his fangs.

Atsushi touched his jaw and pressed against the sharp tooth with his thumb. Dazai shuddered.

“Undress. Now.” Atsushi commanded.

 

The water was warm. The steam slowly filled the room. Atsushi raised his head to let the flow pour over his face and hair. He looked outside the glass shower screen.

Dazai was staring at Atsushi after taking off his pyjamas, his eyes the definition of hunger. His huge cock hung down due to the weight, despite being hard.

“Will you stay there all morning or are you bringing that monstrosity to me?”

“You drool for this monstrosity”

Dazai joined him in the shower, smacked his ass, laughing, and resumed his devotion to Atsushi’s body.

He moved the dripping bangs from Atsushi’s face and kissed his forehead, his cheeks, his mouth. Their lips parted and pressed gently, Atsushi’s soft lips welcoming Dazai’s chapped ones.

Atsushi bared his neck, a gesture of submission that Dazai wasn’t able to do. Dazai held the neck with both hands and latched on it.

Atsushi gasped.

Dazai's tongue licked the drops of water in Atsushi’s skin. A trail of more sloppy kisses turned into teeth scrapes and skin sucking.

Atsushi lowered his hand to Dazai’s cock.

He stroked slowly, too slowly. Dazai jerked forward trying to speed up the pace, Atsushi stopped him stilling his hip with his free hand.

“More” Dazai groaned against Atsushi’s neck.

“Ask nicely”

Dazai applied the slightest pressure to Atsushi’s neck with his hands, and pinched with his teeth the skin right under the jaw, where the jugular starts.

His brain was battling between needing or taking.

Atsushi’s brain just broke for a moment as he felt the little bite.

He let go of the cock and used his hands to move them both away from the water stream, until Dazai’s back bumped the tiles of the shower.

He joined their bodies and thrust, making their bare cocks rub together.

“Ask nicely, alpha

“Fuck me” Dazai answered breathlessly.

He turned around, his back to Atsushi and his hands pressed against the wall. He spread his muscular legs and turned his neck to look at Atsushi with urgency.

Atsushi took his time, sliding his wet cock along Dazai’s ass crack. He whispered in his ear:

“You want your omega to fuck you, uh?”

Dazai’s grunt was obscene.

His alpha’s ego screamed in his mind. He slammed the tiles with an open palm above his head. The thud resounded like a thunder due to the shower’s acoustics.

Atsushi grabbed a bottle of body lotion from one of the shelves. He coated his cock, his hands, and spread Dazai’s cheeks to pump a good load over his hole.

Atsushi’s cock wasn’t really big, but alpha’s bodies weren’t made to take it up the ass, and Dazai didn’t like pain.

He probed the rim with his middle finger. He pumped in and out, bit by bit, keeping the ring lubed all the time so it didn’t hurt.

When the whole finger was inside Dazai, Atsushi circled Dazai’s body with his other hand. He grabbed the hard shaft again.

This time, the pace was nice, pleasuring the man. Atsushi’s hand slid easily from base to tip, applying more pressure in the deflated knot and in the head.

Atsushi rested his head in Dazai’s shoulder, his mouth against the wet skin, and asked:

“You good, love?”

“Go on,” Dazai hummed.

Atsushi mouthed at the skin as he carefully inserted a second finger, stretching the hole with gentleness. The rhythm of the two fingers matched the jerking movement.

He tried a third finger, it was too soon.

Dazai felt too much pressure. He rushed a hand to his behind and waved it, as if asking Atsushi to go slower. Atsushi took the hint.

He circled Dazai’s hole from its inside, applying some force to open the walls. He spread the spare lotion through the ring, to avoid any friction as he kept fingering in and out.

Atsushi loved the weird feeling of fingering, so he knew what felt better. He rubbed the fingers against the side that faced the front of the body, where it was more sensitive.

Dazai’s soft moans became louder. And the third finger slipped inside.

Dazai’s knees shook. So Atsushi removed the fingers and positioned the cock’s lubed tip at Dazai’s entrance.

It went inside smoothly. Atsushi didn’t rush, but focused on the delight of Dazai’s tight walls surrounding him more and more, until his cock was fully buried inside Dazai.

He moaned at the same time Dazai did.

Atsushi released Dazai’s cock because he needed both hands to lift the ass, so he could thrust. Dazai never arched his spine.

Dazai grabbed his own cock. Alphas couldn’t come from prostate stimulation. He jerked the front end, setting a quicker rhythm than Atsushi’s movements.

The two alphas breathed raggedly.

Dazai’s cheek was pressed to the shower, a subtle mark forming in the tiles with every time he breathed out. Atsushi’s mouth warmed Dazai’s shoulder, his little moans a delight to Dazai’s ear.

The hand Dazai had on the steamed shower tiles slipped, his fingers trying to claw at it again. Atsushi intertwined his own hand with Dazai’s and raised it again. Every thrust pushed both hands against the wall.

“I’m… ah… about to…” Dazai warned.

He turned around.

Atsushi groaned as his cock slipped out of Dazai. His instinct craved the pleasure, the temperature change felt like a loss.

Dazai wanted Atsushi to come first. He kissed the man with desire, and pushed his shoulders down to make him sit on the floor.

Then Dazai got on his knees to straddle Atsushi’s legs. He lowered his body as Atsushi aimed at his entrance, fitting the cock inside his ass again.

They hugged. They panted against each other’s necks. The embrace was tender yet passionate.

Dazai supported his weight on his knees and moved up and down fast. He fucked himself while Atsushi thrust up every time Dazai lowered his body.

“Can I... knot you…” Atsushi was breathless.

His knot wasn’t big enough to be unpleasant. Barely wider than his cock.

As an answer, Dazai pushed himself down one last time and just moved his hips against the alpha’s groin.

Atsushi stilled. His cock throbbed as he came with a long groan. His head fell limp against Dazai's chest for a few seconds.

When he recovered, he wanked Dazai’s slippery cock with fast and short movements. He wished he could put his mouth on it, although he didn’t have time.

Dazai came. Atsushi wrapped his hands around the knot, milking it. Dazai’s thick release coated Atsushi’s belly and thighs.

The amount was so abundant that most of the cum seeped through the shower drain.

They slumped against each other for a little until the knot deflated.
